Using the Charger
Each handset is charged using a handset charger. The charger is a compact desktop unit designed to charge and
automatically maintain the correct battery charge levels and voltage.
The charger Handset is powered by AC supply from 110-240VAC that supplies 5.0VDC at 2A.
When charging the battery for the first time, it is necessary to leave the handset in the charger for at least 10 hours
before the battery is fully charged and the handset ready for use.
Handset in the Charger
For correct charging, ensure that the room temperature is between 5°C and 25°C/41°F and 77°F. Do not place the
handset in direct sunlight. The battery has a built-in heat sensor which will stop charging if the battery temperature is
too high.
If the handset is turned off when placed in charger, only the LED indicates the charging. When handset is turned off,
the LED flashes at a low frequency while charging and lights constantly when the charging is finished. There will be
response for incoming calls.
If the handset is turned on when charging, the display shows the charging status.
Handset Serial Number
The serial number (IPEI/IPUI number) of each handset is found either on a label, which is placed behind the battery, or
on the packaging label. First, lift off handset back cover and lift the battery and read the serial number.
The serial number is needed to enable service to the handset. It must be programmed into the system database via
the SME VoIP Configuration interface.
